' Application filed his, 1905. Serial No. 15am .To all whom it may concern:

.Be it known that I, VVILBJURN N. DENNI- BON, a citizen of the United States, and a resident of Camden, State of New Jersey, have invented certain new and useful Improvements intAmplifying-Horns for Talking-Machines, of which the following is a full, clear, and complete disclosure. My invention relates to amplifyinghorns for talking-machines, and more especially to means for detachably mounting the horn u n the machine and for connecting sections oi the horn in a readily-detachable manner,

In the accompanying drawings, which illusinvention, Fige essential parts -machine having my improved orn in use in connection therewit and 2 a bottom plan view of the amplifyling-horn detached from the machine. In t e drawings, the reference-numeral l the motor-casing; 2 the turn-table and record thereon; 3, the sound-box; 4, the tapering hollow ivoted sound box SK?)- porting-tube; 5, t e su porting-bracket or said arm and the am in -hrn; 6, a yoke lifyingiiorn inposition, and 7 a thumb-screw for securing the yoke 6 to the bracket 5.

The. above-described arts are not of'my present invention, whic relates. to the amplifying-horn 11 and the tubular member or sound-conveyer section 8 thereof, being the means by which the horn is supported upon the machine, which in the embodiment .shown consists of a curved or elbow portion having means for engaging a support-for instance, aflange 9, by which it is held upon bracket by oke 6. The section-8 flares outwardly, an its outer end receives the small conical or tape end of the detachable and separable bo y-section 11 of the ,horn, this small end fitt' therein. The section 8, it might be said, orms a art of the horn as well as of the machine, r while it forms the small end portion or section of the" horn as a whole, yet it is secured to a stationary part of the machine and is, in fact means for sup orting the bodv of the ure 1 is a side elevation of t h upon the mac 'ne. In fact, however, the horn consists of these two telescopic sepaiable ta ering sections 8' and 11,,-the larger enter this end of the slot end 0 the former receiving within it the;

small endof the latter, and as a further part of my invention I provide connecting means for these sections comprisiru interenga or interlocking parts carried t rereby. T ese means are u on the large end of section 8 and the small end of section 1 1, and as a preferred, convenient and BifiClGIltCODSi-TUCHOD I employ an inclined slot 10, preferably in section 8, and thelu or pin 12 in section 11.

In assamb ing the sections of the horn the small end of the section 111s inserted within the large end of the section 8, the relative diameters of the parts bein such that the stud will enter the outer on If the parts are then turned relatively axially the pin or big 12 is forced along the slot unt' prevented moving farther by the exterior of of the slot 10.

the section 11 engaging firmly with the interior of the section 8, it being noted that by reason of the pin-and-slot construction the twfi sections are drawn together longitudina y. tion and can only be the operation aboye descri ed.

The interior diameter of the section 8, at the end of the slot adjacent itslarge end, can of course besnfiicieiifto permit the pin to when the parts are brou ht together; but if the material of whic r the section 11 is made is com ressible, as it sometimes is, owing to the t in sheet material composin it, the small end of the section 11 can be si htly compressed, so as to snap the pin intot e upper end ofthe'slot. The section 11 may also be slightly compressed when the pin is being removed from thwslotr Owing to the tapering features of the two sections of the horn, a joint is re uired which will not onl allow the arts to e easily assembled an separated,- ut which will at the 'same tin ehenstron'gt and durable, and such 5 invention in a simple joint is provided by my and eflicisnt manner, and although I have The parts are then held fi fin q dlsengbaged by reversmg 7 shown and described specificallya pin on the small end of the section 11 and an inclined 'slot at the large end of the section 8, yet, ex-- ce'pt'i'n the claims-for this s ecificconstruction, my invention is not limited thereto, but What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. {a sound-conveyer support, a tapering sound -onveyer section mounted thereon, and an amp ifying-horn section detanhahlv IOC mounted upon said conveyer-sectiun, and re movable therefrom while the latter is mounted-upon its su port.

2. An ampliiying-horn consisting of a tapering sound-conveyor section havingmeans for.

' sound-conveyer section having means for enga ing a normally stationary su ort an amplilying-horn section detachal lg mounted upon said conveyer-section, the ends of said conveyer and horn sections telesco ing, and

interlocking means carried by $8.1 sectionsv and ada ted to hold'them in teleseoped' relation, t e said horn-section be ing removable from said conveyer-section while the latter is mounted upon its support.

4. An 'amplifyinghorn consisting of a sound-conveyer section having means'for enp in'g-horn section detacha y mounted upon said conveyer-section, the ends of said conveyer and horn sections telesco ing, and interlocking means carriedby said section and adapted to draw them together longitudinally and hold them in telescoped relation.

5. An amplifying-horn consisting of separable, tapering telescopic sections, oneof said sections having means for enga 'ing a su ort, the small end of one section itting Wit 1n the large end of the other section, a pin or lug carried by one of said sections and adapted to e a e a slot inthe other-of said'sections for 10 ding. the said parts in telescoped relation.

.6. In an amplifying horn, separable, ta: pering, telescopic sections, the lar e end of one section being rovided with a s ot, and the small end of t e other section fittin within the said large end and being provide with a pin or-lug to engage said slot to hold the part in telescoped relation.

7. In an amplifying-horn, separable, tapering, telesco 10 sections, the small end of one section fitting within the large end of the other section, a in or In carriedby one of said sections an adapts to engage an inclined slot in the other of said sections for I holding the said parts in telescoped relation.
